摘要
在对安徽省地热温泉资源分布及其影响因素进行综合分析的基础上,从水温、流量、水化学、热储层等角度系统探讨了全省地热温泉资源的特征,特别是地热温泉的水质类型及功效特征,结果表明:1)安徽省已发现的地热温泉资源主要分布在淮北、沿江、大别山区和皖南山区,其地理分布与地质构造、地层岩性和地形地貌的关系密切,断裂带范围内多温泉出露和人工热水孔,断裂复合交汇处尤多,火成岩、沉积岩岩性对于温泉形成和出露都会产生一定的影响,同时,开发历史、社会需求等方面也会影响温泉资源的选址、开发与规划。2)温泉的水温多为温热水或温水,少数为热水,大部分温泉流量的季节变化不大。3)在水化学特征方面,靠近深大断裂带的温泉水矿化度高,多数属于SO4-Ca-Na型、SO4-Na型或SO4-HCO3-Ca-Na型水,与古老地层及花岗岩岩体有关的温泉属于HCO3-Ca-Na型水,而断陷盆地内的温泉或热水孔多以Cl-Na型水为主;热储层主要有层状、带状、层状兼带状三种类型,其中断陷盆地为层状及层状兼带状,断块隆起带和深大断裂带为带状。4)地热温泉热矿水兼备医疗和保健的理化作用,其中所含的化合物及微量元素对人体的药理和生物功效优于一般的人工水疗及药物浴疗。
Based on the comprehensive analysis of distribution and influencing factors of geothermal hot spring resources in Anhui Province,this paper systematically discusses the characteristics of geothermal hot spring resources in the whole province from the perspectives of water temperature,flow rate,hydro-chemical characteristics and thermal reservoir,especially the water quality types and efficacy of geothermal hot springs.The results show that:1)The geothermal hot spring resources that have been discovered in Anhui are mainly distributed in Huaibei,along the Yangtze River,Dabie Mountain area,and the mountains in the south of Anhui,meanwhile its geographical distribution is closely related to the geological structure,formation lithology,and landform.For instance,exposed hot spring and artificial drilling are mostly distributed in the fault zone,especially in the compound intersection of faults,and the lithology of igneous rock and sedimentary rock will produce certain effect in the formation and exposure of hot springs.At the same time,development history,social demands and other aspects will also influence the sites’selection,development and planning of hot spring resources.2)The water temperature of hot springs is mostly warm water,a few are hot water,and the flow of most hot springs varies little from season to season.3)In terms of hydro-chemical characteristics,hot springs near deep and large fault zones are highly mineralized,and most of them belong to the SO4-Ca-Na type,SO4-Na type or SO4-HCO3-Ca-Na type.Hot springs related to ancient strata and granites belong to the HCO3-Ca.Na type,and the hot spring or hot water hole in the fault basin is dominated by Cl-Na type;there are three types of thermal reservoirs:layered,banded,layered and banded,among which the fault basin is layered,layered and banded,the fault block uplift zone and the deep and large fault zone are banded.4)The heat mineral water of geothermal hot spring has both physical functions of medical treatment and health care.Compounds and trace element
